LDicomAssociate::IsRoleSelect

#include "ltdic.h"

L_BOOL LDicomAssociate::IsRoleSelect(nID)

L_UCHAR nID;

presentation ID

Determines whether Role Selection is enabled for the specified Presentation Context of the DICOM Associate.

Parameter

Description

nID

Presentation ID of the Presentation Context for which you wish to check Role Selection. The presentation ID provides information about both the class type of the data and the transfer syntax to use when transferring the data. It also identifies a specific Presentation Context within an Associate.

Returns

TRUE

Role Selection is enabled for the specified Presentation Context of the DICOM Associate.

FALSE

Role Selection is disabled for the specified Presentation Context of the DICOM Associate.

Comments

If Role Selection is enabled, the role of the specified Presentation Context can be retrieved using LDicomAssociate::GetUserRole and LDicomAssociate::GetProviderRole. To set the role of the specified Presentation Context, use LDicomAssociate::SetRoleSelect.

Example

This example builds an associate request (pointed to by pAssociateAll) that contains all the abstract syntaxes present in m_pDicomAssociate, and adds all the abstract syntaxes not present in m_pDicomAssociate. Each abstract syntax that was not in m_pDicomAssociate is given a default presentation context
